IW-28 SUB/SA-180 Amplifier

Powerful in-wall bass that hides from view
The IW-28 SUB is an in-wall subwoofer that uses dual heavy-duty 8" woofers to deliver rich, vibrant bass to custom-installed audio systems.

Boasting amazing hookup flexibility, the 28 SUB can either be used passively, driven directly off the receiver's front Left/Right speaker outputs by utilizing the 28 SUB's on-board low-pass crossover, OR it can be driven actively by using a power amplifier such as our SA-180 connected to the receiver's 'sub out' jack. The 28 SUB's on-board low-pass crossover is then switched to 'off,' and the crossover functions and bass level duties are handled by the system electronics, as with any powered subwoofer.

Several design features distinguish 28 SUB's amazing performance--its powerful, long-throw woofers, its solid 1"-thick (!) resonant-free MDF baffle, and its audiophile-grade crossover.

This is one serious subwoofer.

The SA-180 monoblock amplifier is the perfect companion to the 28 SUB. With 180 watts of rock-solid RMS power, a massive toroidal transformer, 12-volt trigger turn-on, and 3-position equalization switch, the SA-180 has all the right moves to make the 28 SUB perform at its best.

Our thin bezel design and magnetically attached grille provides a sophisticated and refined look to blend into the wall. Whether it's new construction or retro-fitted into a finished room, the IW-28SUB is one of the most flexible, easy to install, in-wall subwoofers on the market today.
